Uses of Computers

Many people use a bank to keep their money safe. The bank uses a computer to store a list of people and their accounts. When your parents want money to buy you a gift, they go to the bank. The clerk checks on the computer to see if they have enough money in their account. Then the clerk gives the money to your parents. They buy you a gift.

A library stores many books. Searching for your favourite book can take a lot of time. So,

the library uses a computer to store a list of books and their location. When you want to borrow a

book, the librarian can check the computer to see if it is available. Then he can tell you where to find it. He also uses the computer to issue the book to you.

Railways use a computer to book tickets. They also use it to maintain train timings. When you go with your parents to book tickets, the clerk uses the computer to see if seats are available. Then he takes the money and issues the ticket.
